Gene Details:

• MSU gene ID: LOC_Os04g32850
• RAPdb gene ID: Os04g0401000
• Gene Symbol: Pi21
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Wild-type Pi21 appears to slow the plant’s defense responses, which may support optimization of defense mechanisms.
• The resistant Pi21 allele, which is found in some strains of japonica rice, could improve blast resistance of rice worldwide.
• QTL analysis and mapping of Pi21 , a recessive gene for field resistance to rice blast in Japanese upland rice.
• Transcriptome Analysis Highlights Defense and Signaling Pathways Mediated by Rice Pi21 Gene with Partial Resistance to Magnaporthe oryzae.
• The Pi21 gene confers partial and durable resistance to Magnaporthe oryzae.
• However, little is known regarding the molecular mechanisms of resistance mediated by the loss-of-function of Pi21.
• This study highlights possible candidate genes that may serve a function in the partial rice blast resistance mediated by the loss-of-function of Pi21 and increase our understanding of the molecular mechanisms involved in partial resistance against M.
